WP1. Management: Management of the project is critical to success. Managing partners with a very diverse background is a project specific challenge, covered appropriately.

WP2. Infrastructure support: This work package is designed to technically support the setting up and operation of new desktop grids. Both private desktop grids, inside organisations such as universities and research institutes, and public volunteer desktop grids will be supported. This work package will provide and support the related software distributions such as the BOINC distributions and new virtualised solutions, and will assist with their installation and the provision of technical support during their operation based on helpdesks. The work package will also provide technical support for connecting these new desktop grid infrastructures to European e-Infrastructures through the installation of and the provision of operational support for DCI Bridges. Special focus will be on the measurement of energy consumption in co-operation with WP5. The work package gives priory support for the infrastructures which are intended to host applications with citizen-scientists.

WP3. Addressing citizens: Increasing the number of volunteers donating computing time to science will be the most important objective of this work package. It will do so by helping the Desktop Grids from the project partners and of IDGF members, by developing joint (between the Desktop Grid operators) campaigns, setting up a network of citizen scientists as (local) help and "ambassadors". It will strengthen the relationship with other citizen science and science promoting organisations. WP3 will also maintain and edit the portal (localizable in more languages) and produce supporting materials to promote Desktop Grids amongst citizens. The Work Package will also take care of the dissemination activities of the project itself. WP3 will use the infrastructure provides by WP2. It will use the information and data produced by WP5. It will collaborate with WP4 on common promotional activities and on setting up hybrid private/volunteer Desktop Grids.

WP4. Addressing scientific organisations: WP4 is designed to create awareness amongst scientific organisations, and also amongst user communities and application developers representing these organisations. The work package will also disseminate project results and provide training for the above communities. One of the most important objectives of WP4 is to support scientific organisations in setting up local desktop grid infrastructures. These infrastructures could be utilised by local researchers for running scientific applications, and could also increase the awareness amongst students and employees of these organisations regarding the importance and applicability of desktop grid technology. This latter could lead to a new generation of donors (or "citizen scientists") for public desktop grid infrastructures. WP4 will support scientific end-users and application developers in developing, testing, validating and operating their applications on the production infrastructure. The application porting process will utilise the IDGF Application Development Methodology and the Application Porting Infrastructure operated by WP2. Following the successful testing and (if required) validation phases, WP4 will support the user community in deploying and operating the application on the production infrastructure. WP4 will operate a central IDGF helpdesk and co-ordinate the operation of local 2nd tier helpdesks to support the user communities on a daily basis. WP4 will also organize training courses for different audiences (end-users, application developers and system administrators, future trainers, and will maintain and publish IDGF training materials.

WP5. Analysis: WP5 covers two aspects that are crucial to the further development of desktop grids: the green and the financial aspect. The work package includes studies to obtain more detailed information about the actual energy consumptions of Desktop Grids so that fact-based comparisons can be made with other computing infrastructures. We will also evaluate technologies that may reduce this energy further and, possibly, integrate energy-saving techniques into the Desktop Grid infrastructure. In particular, we will test the slow background computing technique proposed by SONY. WP5 also includes the performance/energy evaluation of new platforms, such as mobile devices, and analyze whether these devices can improve the footprint of Desktop Grids. WP5 also covers an analysis of the financial aspects of Desktop Grids. We will gather data and build simplified models to evaluate the financial benefits of Desktop Grids. The analysis of the green and the financial aspects are essential prerequisites to convince organizations and volunteers to participate in Desktop Grids.
